Council meetings are open to the public unless a valid reason for exclusion is given, and the agenda and summons must specify the location. Virtual meetings have recently been permitted, as legislation, has been changed but they have to take place at a designated location. The only legal way that might be acceptable w to permit public participation would be to live stream the meeting, in which case the streaming URL would be the location. If cllrs won',t avail themselves with technology, you could argue they are failing to serve their partitioners.
